Abstract (en)

[origin: WO2016020889A1] An apparatus for oxidation of a C8-C12 alkylbenzene reactant to a C8-C12 alkylbenzene hydroperoxide product, the reactor can comprise: a flow reactor comprising a reactant inlet, an oxidate product outlet, wherein the reactor is configured to provide a liquid flow from the reactant inlet to the product outlet, a gas inlet configured to introduce an oxygen-containing gas into the reactor, and an inlet sparger configured to flow gas bubbles comprising the oxygen-containing gas within the liquid flow, and wherein: the inlet sparger is configured to flow the gas bubbles having a diameter of 1.0 mm to 5.0 mm over a gas bubble residence time from 1 to 200 seconds, and/or the inlet sparger configured to flow the gas bubbles such that greater than or equal to 80% of the gas bubbles do not coalesce into larger bubbles over a gas bubble residence time of 1 to 200 seconds.
